If you're not particularly familiar with Python, then it may be easier to write the pass directly in C. > Also please let me know some references on how to write a new PASS > within GCC codebase? If you're new, it's probably easiest to do it within a plugin, see: http://gcc.gnu.org/wiki/plugins http://gcc.gnu.org/onlinedocs/gccint/Plugins.html LWN had an excellent tutorial on creating a new gcc pass via a plugin here: https://lwn.net/Articles/457543/ [1] Hope this is helpful Dave [1] fwiw I ported the example from the tutorial to Python here: http://gcc-python-plugin.readthedocs.org/en/latest/working-with-c.html#spell-checking-string-constants-within-source-code
